Tunneling Applications and Considerations JN0-352 Practice Questions (Page 1)
Part of the Tunnels domain, which makes up ~7% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~2–4 in this domain), expect 1–1 from this objective — we provide 17 practice questions to prepare you well beyond it.

A network engineer is evaluating two tunnel options for connecting two remote sites over a WAN link with a 1500-byte MTU. Option 1 uses GRE with a 24-byte overhead, and Option 2 uses IP-IP with a 20-byte overhead. The engineer must ensure that the maximum-sized IP packet from the LAN can traverse the tunnel without fragmentation. What is the largest IP MTU that can be configured on the tunnel interfaces to meet this requirement?

A company is connecting two branch offices over the internet. The branch offices use private IP addresses, and the company wants to encrypt all traffic between them. The engineer must choose a tunneling technology that provides encryption and can carry the private IP traffic. Which technology should the engineer select?

A network architect is designing a tunnel between two sites over a public WAN. The traffic includes both latency-sensitive VoIP and bulk file transfers. The architect must ensure that VoIP packets are not delayed behind large file-transfer packets inside the tunnel. Which tunneling consideration should the architect prioritize in the design?

A service provider is deploying a new IPv6-only backbone but must continue to carry IPv4 traffic from existing enterprise customers. The provider wants to encapsulate IPv4 packets inside IPv6 for transport across the backbone, with minimal configuration on the customer edge devices. Which tunneling approach should the provider implement?
